The board:

Aux Molex plug is to supply additional power to PCI-E slots. Placement is pretty poor- its beside the 24-pin ATX plug!

6 S-ATA ports are controlled by ICH9R chipset, with an additional 2 controlled by a Jmicron chip. (Called “Gigabyte RAID”)

compared to what I got on the P965/ ICH8R:

6-phase CPU power. Gigabytes top-end board the DQ6, has 12 power phases. This should not matter much at all. The components used on both boards are the same, but in general, it’s the quality of the phases that counts, not the quantity. Intel spec states that the minimum phase count is 4.

The CPU socket center is very sp****ly populated. Only 4 caps present here, out of a possible 18. Not sure what to think of this. It shouldn’t affect stability much, but time will tell. On the plus side, the CPU area is good for extreme cooling solutions. Some air coolers might have narrow clearance margins due to the shape of the NB heatpipe solution, but I cannot comment as I don’t use air cooling for Intel CPUs. Ever.

The NB and SB heatsink assemblies are bolted to the board, instead of the usual plastic clips or hooks. Nice touch. The rear of the NB and SB areas (on the back of the board) have small heatsinks as well, which may or may not help cooling, but hinder heatsink changes slightly. The VRM sinks revert to sprung plastic clips though.

The 8-pin CPU power plug is located between 2 section of the heatpipe assembly. It shouldn’t be too hard to reach or work with though. Four of the 8 pins are masked off to make sure users with a 4-pin CPU plug don’t use the wrong side.

Sound comes from a Realtek RTL 889A chip. Nothing spectacular, but I’m hoping this sounds better than the recent Asus offerings, which produced too much crackle for my liking.

Generally the board layout is good. Gigabyte have already had time with this general layout when designing the P965 boards. A few tweaks here and there have been made, but the ground-work already done helps explain why these boards have been so fast to market.

Maximum Available Voltages:
CPU: 2.35V (yes...>>2V!)
MCH: +0.375V
FSB: +0.35V
PCI-E: +0.35V
DDR2: +1.55V (from 1.80V standard) (yes... 3.35V is an option!)


Primary running notes: I installed windows with the CPU at 400x8. We can thus mark 400FSB off as easy. The 2nd thing to strike home is how cool...no -COLD- this chipset appears to run. Some might assume this means the heatpipes are doing their job. This is not the answer- the NB/SB combo spit out so little heat that the heatpipe solution is absolute overkill. Once initial testing is done I will make sure heatsink contact is good.

some Multimeter probing on the board soon zeroed in on the voltage readpoints. Setting 2.10 volts for the RAM (+0.3V)gives a real voltage of 2.165V so the general tracking looks pretty average.

I`m still working on read-points. Should have most of the important ones done within a couple hours, then onto FSB testing :)

The audio quality is much much cleaner than the recent Asus solutions. Bass does not distort and the bottom end of music seems a bit fuller.

Update: VMCH seems a bit hit n miss with each BIOS step, adds 0.05V if +0.15V is added, and adds 0.25V if +0.25V is requested

450FSB needs an MCH and FSB voltage bump. Still fine-tuning ideas- I know the board has a load more in it :)

EDIT 2:

480FSB seems fine, 500 doesnt want to play. I suspect my E67 is the wall here, and will put me around 492FSB but i`m not done yet.

Droop and VCore: 1.45V BIOS gives 1.452V windows idle and 1.451V SuperPi. 100% load gives: 1.451V. Voltage readpoint was taken from one of the missing CPU Inductor points.

SuperPi: still working on combos at 3600MHz. Best 1M so far at 400x9 is 14.062 secs, not tweaked.

Memset values dont match all the BIOS value, and vice-versa. In F4 BIOS, I cant see tRFC or refresh-refresh delay options! They naturally default to slack numbers depending on RAM multiplier/RAM MHz so I know theres a performance hit there.

Having some trouble getting to the VDIMM pins for a direct measurement m3kk, but i`ll work at it.

EDIT 3:

Swapped chips- 500FSB is a piece of cake but I suspect this CPU hits a wall too, just after 500FSB. Will try FSB again next time I have Dry Ice.

Updated BIOS to F5d (from F4) Not noticing any big differences.

I want to buy this board too.

Please check the vdrop.
Can you measure the VDIM directly from the memory slot?
And please run a Pi1M and a Pi32M with 3600 MHZ CPU speed.

Thanks and good luck.

The full review for extreme overclocker must consist of :

[V]voltage options, Vdrop
[X]tweaking abilities,special features
[X]max FSB stable with Dual and Quad core
[X]performance at certain freq comparing with other mobos

Just joking :D

Nice review, looking forward to continuation :ocx44:

1st post updated. I`ll try to get most info into 1st post.

Sorry buttertoast, no Quad here :(

(donations gratefully accepted! :D)

voltage options/droop...done!

tweaking....still working on it

Special features.....probably none, though I dont mean it in a bad way... its not particularly flash, just a solid board. It shuts down fully when the FSB/multi settings are changed, like the P5B

FSB... 480+++ (depending on chip)

performance per clock...working on it :D

Dont say ur joking bro, what you asked for should be an important part of any mobo review! :)

This f***ing sucks. I cant clock RAM for s*** on this board! Cant get past 540MHz 5-5-5 with any combo of FSB and multi- any tighter and windows thinks its lost a /system32 file. 600MHz is a fantasy from here. The RAM is fine- clocks like it should on the P5N32-E Plus.

I must be the only guy on planet f***ing earth who gets better SPi32M times under 650I than P35.

sorry!

Very appreciated that you are pointing these issues out. I am also looking at this board and am watching with a keen eye:)

Great job matehttp://img54.exs.cx/img54/2200/rockon5nk.gif

Been working on RAM clocking over the weekend- I gotta say I really dont think the BIOS' are tuned for good RAM clocking. (have tried F3 F4 and F5d.) I hit 540MHz at 450 FSB 4-4-4-4-22 and a 550 or 555MHz run probably at the same RAM/FSB ratio but I cant find the screeny. Thats as good as its been. 2.45V real, 5-5-5 wont do 600MHz. I wont try anything slacker.

Some have suggested the internal latencies are tighter so 550MHz 4-4-4 will perform like e.g... 600MHz 4-4-4 on a 965 but I cant say I feel that way.

will try slacking the tRAS off more but i`m not holding my breath
